Abstract
In this letter a novel microfluidic reconfigurable filter is presented at 1, 1.4 and 1.8 GHz. This triple band filter is based on dual-mode ring resonators where metal-liquid switches are used for interconnection of different resonators and feed lines, therefore, allowing tuning of its center frequency as well as of its external Q. Simulated and experimental results are shown with good agreement.
